Lophophine
Lophophine (MMDPEA or 3-methoxy-4,5-methylenedioxyphenethylamine) is a putative psychedelic and entactogen drug of the methylenedioxyphenethylamine class. It is the α-demethylated homologue of MMDA, and is also closely related to mescaline. Alexander Shulgin originally suggested that lophophine may be a natural constituent of peyote (''Lophophora williamsii'') due to it being the only logical chemical intermediate for the biosynthesis of several tetrahydroisoquinolines known to be present in this cactus species. Subsequently, lophophine was indeed shown to be a minor component of both peyote and San Pedro cactus. Shulgin reports that lophophine is active in the dosage range of 150–250 mg. He states that at these doses, lophophine has some similarity to mescaline in action, in producing a peaceful elevation of mood, euphoria, and mild enhancement of visual perception, but without the generation of closed-eye mental imagery. Shulgin also notes that (in contrast to m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Substituted Methylenedioxyphenethylamine
Substituted methylenedioxy- phenethylamines (MDxx) are a large chemical class of derivatives of the phenethylamines, which includes many psychoactive drugs that act as entactogens, psychedelics, and/or stimulants, as well as entheogens. These agents are used as research chemicals, designer drugs and as recreational substances. The base compound of the MDxx class is 3,4-methylenedioxyphenethylamine (MDPEA), and the prototypical agent of this class is 3,4-methylenedioxy-''N''-methylamphetamine (MDMA; "ecstasy"). Other mentionables include 3,4-methylenedioxyamphetamine (MDA), 3,4-methylenedioxy-''N''-ethylamphetamine (MDEA; "Eve"), ''N''-methyl-1,3-benzodioxolylbutanamine (MBDB; "Eden"), and 3,4-methylenedioxy-''N''-methylcathinone (βk-MDMA; "Methylone"). List of substituted methylenedioxyphenethylamines The compounds most commonly regarded as comprising the family of MDxx derivatives include: Related compounds In addition, there are a number of other compounds that ...

3-methoxy-4,5-methylenedioxyamphetamine
MMDA (3-methoxy-4,5-methylenedioxyamphetamine; 5-methoxy-MDA) is a psychedelic and entactogen drug of the amphetamine class. It is an analogue of lophophine, MDA, and MDMA. MMDA was described by Alexander Shulgin in his book '' PiHKAL''. Shulgin lists the dosage range of MMDA as 100–250 mg. The first effects appear within 30–60 minutes following oral administration. MMDA produces euphoria and loving warmth, and attenuates feelings such as anxiety and loneliness. MMDA also produces closed eye visuals, a state of drowsiness, muscle relaxation, and time distortion. Side effects include moderate mydriasis, dizziness, sensations of heat or cold, and trembling. The imagery is generally realistic, and often related to everyday perception of people, landscapes, or objects. The effects of MMDA usually reach a peak during the first hour following the initial effects, and begin to wane during the second hour, and usually completely disappear by the end of the fifth hour.

Phenethylamines
Substituted phenethylamines (or simply phenethylamines) are a chemical class of organic compounds that are based upon the phenethylamine structure; the class is composed of all the derivative compounds of phenethylamine which can be formed by replacing, or substituting, one or more hydrogen atoms in the phenethylamine core structure with substituents. The structural formula of any substituted phenethylamine contains a phenyl ring that is joined to an amino (NH) group via a two-carbon sidechain. Hence, any substituted phenethylamine can be classified according to the substitution of hydrogen (H) atoms on phenethylamine's phenyl ring, sidechain, or amino group with a specific group of atoms. Many substituted phenethylamines are psychoactive drugs which belong to a variety of different drug classes, including central nervous system stimulants (e.g., amphetamine), hallucinogens (e.g., dl- 2,5-dimethoxy-4-methylamphetamine DOM), entactogens (e.g., 3,4-methylenedioxyamphe ...

3,4-Methylenedioxyphenethylamine
3,4-Methylenedioxyphenethylamine, also known as 3,4-MDPEA, MDPEA, and homopiperonylamine, is a substituted phenethylamine formed by adding a methylenedioxy group to phenethylamine. It is structurally similar to MDA, but without the methyl group at the alpha position. According to Alexander Shulgin in his book '' PiHKAL'', MDPEA appears to be biologically inactive. This is likely because of extensive first-pass metabolism by the enzyme monoamine oxidase. However, if MDPEA were either used in high enough of doses (e.g., 1-2 grams), or in combination with a monoamine oxidase inhibitor (MAOI), it is probable that it would become sufficiently active, though it would likely have a relatively short duration of action. This idea is similar in concept to the use of selective MAOA inhibitors and selective MAOB inhibitors in augmentation of dimethyltryptamine (DMT) and phenethylamine (PEA), respectively.

Nausea
Nausea is a diffuse sensation of unease and discomfort, sometimes perceived as an urge to vomit. While not painful, it can be a debilitating symptom if prolonged and has been described as placing discomfort on the chest, abdomen, or back of the throat. Over 30 definitions of nausea were proposed in a 2011 book on the topic. Nausea is a non-specific symptom, which means that it has many possible causes. Some common causes of nausea are gastroenteritis and other gastrointestinal disorders, food poisoning, motion sickness, dizziness, migraine, fainting, low blood sugar, anxiety, and lack of sleep. Nausea is a side effect of many medications including chemotherapy, or morning sickness in early pregnancy. Nausea may also be caused by disgust and depression. Medications taken to prevent and treat nausea and vomiting are called antiemetics. The most commonly prescribed antiemetics in the US are promethazine, metoclopramide, and the newer ondansetron. The word nausea is from Lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mental Imagery
A mental image is an experience that, on most occasions, significantly resembles the experience of 'perceiving' some object, event, or scene, but occurs when the relevant object, event, or scene is not actually present to the senses. There are sometimes episodes, particularly on falling asleep ( hypnagogic imagery) and waking up ( hypnopompic imagery), when the mental imagery may be dynamic, phantasmagoric and involuntary in character, repeatedly presenting identifiable objects or actions, spilling over from waking events, or defying perception, presenting a kaleidoscopic field, in which no distinct object can be discerned. Mental imagery can sometimes produce the same effects as would be produced by the behavior or experience imagined. The nature of these experiences, what makes them possible, and their function (if any) have long been subjects of research and controversy in philosophy, psychology, cognitive science, and, more recently, neuroscience.

Closed Eye Hallucinations
Closed-eye hallucinations and closed-eye visualizations (CEV) are hallucinations that occur when one's eyes are closed or when one is in a darkened room. They can be a form of ''phosphene''. Some people report CEV under the influence of psychedelics; these are reportedly of a different nature than the "open-eye" hallucinations of the same compounds. Similar hallucinations that occur due to loss of vision are called ''visual release hallucinations''. Levels of CEV perception There are five known levels of CEV perception which can be achieved either through chemical stimuli or through meditative relaxation techniques. Level 1 and 2 are very common and often happen every day. It is still normal to experience level 3, and even level 4, but only a small percentage of the population does this without psychedelic drugs, meditation or extensive visualization training. Level 1: Visual noise The most basic form of CEV perception that can be immediately experienced in normal waking con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetrahydroisoquinoline
Tetrahydroisoquinoline (TIQ or THIQ) is an organic compound with the chemical formula C9H11N. Classified as a secondary amine, it is derived from isoquinoline by hydrogenation. It is a colorless viscous liquid that is miscible with most organic solvents. The tetrahydroisoquinoline skeleton is encountered in a number of bioactive compounds and drugs. Reactions As a secondary amine, tetrahydroisoquinoline has weakly basic properties and forms salts with strong acids. It can be dehydrogenated to give isoquinoline and hydrogenated to decahydroisoquinoline. Like other secondary amines, tetrahydroisoquinoline can be oxidized to the corresponding nitrone using hydrogen peroxide, catalyzed by selenium dioxide. Toxicology Tetrahydroisoquinoline derivatives may be formed in the body as metabolites of some drugs, and this was once thought to be involved in the development of alcoholism. This theory has now been discredited and is no longer generally accepted by the scientific community, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perception
Perception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system.Goldstein (2009) pp. 5–7 Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves. Perception is not only the passive receipt of these signals, but it is also shaped by the recipient's learning, memory, expectation, and attention. Gregory, Richard. "Perception" in Gregory, Zangwill (1987) pp. 598–601. Sensory input is a process that transforms this low-level information to higher-level information (e.g., extracts shapes for object recognition). The process that follows connects a person's concepts and expectations (or knowledge), restorative and selective mechanisms (such as ...

Visual
The visual system comprises the sensory organ (the eye) and parts of the central nervous system (the retina containing photoreceptor cells, the optic nerve, the optic tract and the visual cortex) which gives organisms the sense of sight (the ability to detect and process visible light) as well as enabling the formation of several non-image photo response functions. It detects and interprets information from the optical spectrum perceptible to that species to "build a representation" of the surrounding environment. The visual system carries out a number of complex tasks, including the reception of light and the formation of monocular neural representations, colour vision, the neural mechanisms underlying stereopsis and assessment of distances to and between objects, the identification of a particular object of interest, motion perception, the analysis and integration of visual information, pattern recognition, accurate motor coordination under visual guidance, and more.

Euphoria (emotion)
Euphoria ( ) is the experience (or affect) of pleasure or excitement and intense feelings of well-being and happiness. Certain natural rewards and social activities, such as aerobic exercise, laughter, listening to or making music and dancing, can induce a state of euphoria. Euphoria is also a symptom of certain neurological or neuropsychiatric disorders, such as mania. Romantic love and components of the human sexual response cycle are also associated with the induction of euphoria. Certain drugs, many of which are addictive, can cause euphoria, which at least partially motivates their recreational use. Hedonic hotspots – i.e., the pleasure centers of the brain – are functionally linked. Activation of one hotspot results in the recruitment of the others. Inhibition of one hotspot results in the blunting of the effects of activating another hotspot. Therefore, the simultaneous activation of every hedonic hotspot within the reward system is believed to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
